Emotion analysis in children through facial emissivity of infrared thermal imaging

Recovering Surface Temperature and Emissivity from Thermal Infrared Multispectral Data

In 1992 Thermal Infrared Multispectral Scanner (TIMS) ferent lines on the same day. However, there are differdata were acquired from the NASA C-130 aircraft over ences when the same area is seen on the two days espethe Sahelian region of West Africa as part of the Hydrocially for the low emissivity values. Some of these logical and Atmospheric Pilot Experiment in the Sahel differences may be du...

A Thermal Facial Emotion Database and Its Analysis

In recent years, thermal image has extensively been used in many fields such as military (e.g., target acquisition, surveillance, night vision, homing and tracking) and civilian purposes (e.g., medical diagnosis, thermal efficiency analysis, environmental monitoring). It may be a promising alternative for investigation of facial expression and emotion. Currently there are very few database to s...

Digital Infrared Thermal Imaging

Infrared thermal imaging in medicine.

This review describes the features of modern infrared imaging technology and the standardization protocols for thermal imaging in medicine. The technique essentially uses naturally emitted infrared radiation from the skin surface. Recent studies have investigated the influence of equipment and the methods of image recording. The credibility and acceptance of thermal imaging in medicine is subje...

Errors analysis on temperature and emissivity determination from hyperspectral thermal infrared data.

Sensitivity analysis of temperature-emissivity separation method commonly applied to hyperspectral data to various sources of errors is performed in this paper. In terms of resulting errors in the process of retrieving surface temperature, results show that: (1) Satisfactory results can be obtained for heterogeneous land surfaces and retrieval error of surface temperature is small enough to be ...
